Aragorn is a fictional character and a protagonist in J. R. R. Tolkien's The Lord of the Rings. Aragorn was a Ranger of the North, first introduced with the name Strider and later revealed to be the heir of Isildur, an ancient King of Arnor and Gondor. Aragorn was a confidant of the wizard Gandalf, and played a part in the quest to destroy the One Ring and defeat the Dark Lord Sauron. As a young man, Aragorn fell in love with the immortal elf Arwen, as told in "The Tale of Aragorn and Arwen". Arwen's father, Elrond Half-elven, forbade them to marry unless Aragorn became King of both Arnor and Gondor.
Aragorn led the Fellowship of the Ring following the loss of Gandalf in the Mines of Moria. When the Fellowship was broken, he tracked the hobbits Meriadoc Brandybuck and Peregrin Took with the help of Legolas the elf and Gimli the dwarf to Fangorn Forest. He then fought in the battle at Helm's Deep and the Battle of the Pelennor Fields. After defeating Sauron's forces in Gondor, he led the armies of Gondor and Rohan against the Black Gate of Mordor, distracting Sauron's attention and enabling Frodo Baggins and Samwise Gamgee to destroy the One Ring. Aragorn was proclaimed King by the people of Gondor, and crowned King of both Gondor and Arnor. He then married Arwen and ruled for 122 years.
Tolkien developed the character of Aragorn over a long period, beginning with a hobbit nicknamed Trotter and trying out many names before arriving at a Man named Aragorn. Commentators have proposed historical figures such as King Oswald of Northumbria and King Alfred the Great as sources of inspiration for Aragorn, noting parallels such as spending time in exile and raising armies to retake their kingdoms. Aragorn has been compared to the figure of Christ as King, complete with the use of prophecy paralleling the Old Testament's foretelling of the Messiah. Others have evaluated his literary status using Northrop Frye's classification, suggesting that while the hobbits are in "Low Mimetic" mode and characters such as Éomer are in "High Mimetic" mode, Aragorn reaches the level of "Romantic" hero as he is superior in ability and lifespan to those around him.
Aragorn has appeared in mainstream films by Ralph Bakshi, Rankin/Bass, and the film trilogy by Peter Jackson, and in the fan film The Hunt for Gollum. He has also appeared in the BBC radio dramatisation of The Lord of the Rings.
